Title: Transition controlled balanced encoding scheme
Inventor: LEE KYEONGHO
IPC: H03M7/00
Filed: 1997-03-25
Abstract: A method and apparatus for producing a transition-controlled, DC-balanced sequence of characters from an input sequence of data bytes is disclosed herein. The bits in each of the data bytes are selectively complemented in accordance with the number of logical '1' signals in each data byte in order to produce selectively complemented data blocks. A cumulative disparity is then determined between the logical values of different type included within ones of the selectively complemented data blocks previously encoded into characters. In addition, a current disparity in a candidate character associated with a current one of the selectively complemented data blocks being encoded is also determined. The candidate character is assigned to the current one of the selectively complemented data blocks if the current disparity is of a polarity opposite to a first polarity of the cumulative disparity.      Alternately, the complement of the candidate character is assigned to the current one of the selectively complemented data blocks if the current disparity is of the first polarity. In a high-transition mode of operation, the bits within data blocks including fewer than a minimum number of logical 'I' signals ate selectively complemented so that each such selectively complemented data block includes in excess of the minimum number of logical transitions. In a low-transition mode of operation, the bits within data blocks having more than a predefined number of logical 'I' signals are selectively complimented so that each such selectively complemented data block includes less than the maximum number of logical transitions.

Filed: 2001-10-18
Abstract: A method for the determination of concentrations of analytes, e. g., glucose , and other metabolites in human tissue, wherein the temperature of a defined cutaneous volume of tissue is controlled. The method involves calculating th e concentration of an analyte in the tissue by taking into consideration the values of optical parameters of a sample of tissue measured in the defined cutaneous volume of the tissue at various temperatures. The selection of the  defined volume is a function of the sampling distance along the surface of t he tissue, the wavelength of light used to illuminate the tissue, and the temperature in the defined volume of tissue, which is a function of the temperature at the surface of the tissue. In an embodiment of the method of this invention, the temperature of the defined cutaneous volume of the tissu e is varied within a defined physiological range to change the depth of penetration of light into the tissue, thereby achieving a depth profile for the optical signal. The method of this invention utilizes changes in temperature and selection of wavelengths to define cutaneous volumes below t he surface of the tissue, in which volumes the concentration of an analyte can be determined.
